Free and Open Another reason there are so many audio codecs: silly licensing restrictions. Would you base a business on technology a competitor controls? That's why the Opus specification and complete source are Free, Open, and available for any use whatsoever without IP restrictions, explicit licensing or royalties. Opus was developed and tested in a public, fully transparent process within the IETF, proof that open collaboration can produce a better audio codec than proprietary, secretive, patent-encumbered systems. Open standards benefit-- and benefit from-- open source organizations and traditional commercial software companies alike. Opus itself is the result of a collaboration including Broadcom, Google, the IETF, Microsoft (through Skype), Mozilla, Octasic and Xiph.Org.

You may remember a high-profile, landmark ruling last year in Massachusetts, where charges against Simon Glik -- arrested for violating a state law that said it's "wiretapping" to record a police officer in public without his permission -- weren't just dropped, but the arrest was found to be both a First and Fourth Amendment violation. In the end, Boston was forced to pay Glik $170,000 for violating his civil rights. You would think that story would spread across Massachusetts pretty quickly and law enforcement officials and local district attorneys would recognize that filing similar charges would be a certified bad idea. Not so, apparently, in the town of Shrewsbury. Irving J. Espinosa-Rodrigue was apparently arrested and charged under the very same statute after having a passenger in his car videotape a traffic stop for speeding, and then posting the video on YouTube. Once again, the "issue" is that Massachusetts is a "two-party consent" state, whereby an audio recording can't be done without first notifying the person being recorded, or its deemed a "wiretap." This interpretation, especially when dealing with cops in public, is flat-out ridiculous and unconstitutional, as the Glik ruling showed.

Here, we describe a new acoustic cryptanalysis key extraction attack, applicable to GnuPG's current implementation of RSA. The attack can extract full 4096-bit RSA decryption keys from laptop computers (of various models), within an hour, using the sound generated by the computer during the decryption of some chosen ciphertexts. We experimentally demonstrate that such attacks can be carried out, using either a plain mobile phone placed next to the computer, or a more sensitive microphone placed 4 meters away.

Some of these DMCA rules outline restrictions on the frequency some songs can be played. In any 3-hour period, we can webcast: No more than 3 songs from one album;no more than 2 played consecutively No more than 4 songs from a set/compilation;no more than 3 played consecutively No more than 4 recorded songs by the same artist(live studio appearances are okay)
